At this point, I don't think a single person with a 370 has gotten a CEL from the Berk HFCs. All this talk about a fix is merely hypothetical at this point, i.e., what to do if and when we get a CEL. (I'm also the guy who said that CELs just come w/ the territory.)

Of course there are always other reasons, no one ever doubted that. However, the majority of people are looking for maximum gain(95+%).
I've had both(pipes and HFC's) on various cars and I've always thrown a CEL....every last time.
If it doesn't happen with the 370Z than that's a great thing, but I think it's way too early to even make it seem like a code will not be thrown.
